Spatial coherence measurement through Fourier transform of intensity of diffraction fringes of a 1D step in reflection

In this paper, we present a new method for measuring the spatial coherence of optical beams by utilizing the Fresnel diffraction patterns formed by a 1D phase step in reflection. The spatial coherence function is obtained from the ratio of the amplitude of Fourier transform of the intensity distribu...
